Cricket ACT launched its competitive summer on Thursday as heavy rain tumbled from a grey sky, having been largely absent during more than two months of the Territory's restrictive lockdown.

And with dubious weather forecast to persist over the next 48 hours, it means the opening round of men's cricket, and the newly minted women's second grade competition, are in danger of being washed out.

It comes after months of planning a pathway out of lockdown for grade cricket, which had initially been slated to not start until mid-November.

"It's been getting worse and worse each time I look at it," Ginninderra captain Rhys Healy said.

"It's just the way things go, you're looking at a shortened season, we haven't played any sport for four months."

Up to 45mm of rain were tipped to fall in parts of Canberra on Thursday.

MORE CANBERRA SPORT

Another 15mm could land on Friday before things ease off, but by then it may be too late for Canberra's cricket grounds, which have laid dormant for months, to dry in time.

That would reduce an already truncated season, which will include just three regular-season two-day matches this summer.

It also further delays Cricket ACT's second-tier women's competition, launched before lockdown and designed to encourage further participation in the senior ranks without the need to compete against seasoned Meteors players.

"The rain has happened to all of us before but I think we'll get through it, it'll just be more exciting for the next game I reckon," Queanbeyan captain Alana Horsfall said.

"It's been hard [during lockdown] but there's still lots of things open in Canberra which you just had to do with small amounts of people, and work on your individual skills."

Weston Creek Molonglo's women's team stayed sane during the lockdown by sharing their training sessions via the Strava app, according to captain Kelly Rowlings.

"We've got groups on Strava and we all follow each other and it was our social media of choice during the lockdown, just to keep up with everyone's times and making sure everyone was staying active," last season's grand final hero Rowlings said.

"There was a bit of banter thrown around and a few jokes made and now it's pretty much our social media of choice which is weird, because we're all quite young so we should be on Instagram and Snapchat, but it was Strava."

Just as sanity was set to be restored, rain turned up to spoil the parade with teams across Canberra preparing to activate their wet weather changeroom plans.

"I've got Uno cards in my kit at all times," Rowlings said.

"There's a bit of hallway cricket with the tennis ball. There's a bit of dancing actually, that's probably what our club does the most is singing and dancing, we've always got a speaker handy we just kind of sit around and vibe together."

Healy said his side was also keen on hallway cricket to pass the time.

"That's usually what happens, they can play for hours," Healy said.

"They've got a batting order rotation worked out - that's how we keep it interesting. A couple of years ago, one of the boys said he was more devastated when he got out in corridor cricket than when he got out in the actual game."
